Best answer
Right option is (c) Horizontal boring mill type

The explanation: Bridge type CMM is more difficult to load. It less sensitive to mechanical errors. Horizontal boring mill type is best suited for heavy and large workpieces. Highly accurate type is vertical bore mill type but is usually slower to operate.
